Goettsch Partners has been commissioned by Guangzhou R&F Properties Co. to design a new 1,000-foot-tall mixed-use building in Guangzhou, China. The project totals 1,878,000 square feet and features a 180-key Park Hyatt hotel, 430,000 square feet of offices, 65,000 square feet of retail, 24 condominiums, 174 serviced apartments, and underground parking for 700 cars.The 66-storey building is located in the Zhujiang development, planned as Guangzhou’s new city center, near the Pearl River. The tight, two-acre site sits over a transit station at the intersection of two subway lines, with neighboring buildings that include the Grand Hyatt Guangzhou, also designed by Goettsch Partners; the city’s new opera house; the new Guangdong Museum; and what will be China’s tallest twin towers at more than 1,300 feet.The Park Hyatt tower is designed as a single volume that pinches in at the corners in relation to the changing programmatic functions stacked within. The field of staggered vertical strips on the façade stretches and compresses like tendons in response to the varying floor-to-floor heights required for each distinct function. The approximately $150 million project is currently in the schematic design phase and is expected to be completed in 2010.
